Hello All ---
Is it possible to disable a row or number of (specific) rows in a ListBox
without disabling the entire ListBox?
i think you have to do this manually.
you either create a cellrenderer for your list and handle it this way (look in the help for
cellRenderer API) or you could :
var list:mx.controls.List;
list.addItem({label:"Flash", data:{value:1, enabled:true}} );
/**/
list.addItem({label:"Dreamweaver", data:{value:2, enabled:false}} );
list.addItem({label:"ColdFusion", data:{value:3, enabled:true}} );
function onListClick (evt:Object)
{
var list = evt.target;
//
if (!list.selectedItem.data.enabled)
{
list.selectedIndex = undefined;
list.invalidate();
trace ("this item is disabled")
}
else
{
trace ("you selected: " + list.selectedItem.label)
}
}
function onListRollOver(evt:Object)
{
var list = evt.target;
var ix = evt.index;
var item = list.getItemAt(ix);
var curCol = list.getStyle("backgroundColor"); // be aware of "alternatingRowColors", you'd
have to check here if ix is odd or even, also you should check that there's no cutom
cellrenderer here
//
if (!item.data.enabled)
{
list.setPropertiesAt(ix, {backgroundDisabledColor:curCol});
list.invalidate();
}
else
{
trace ("you hovered: " + list.selectedItem.label);
}
}
list.addEventListener ('change', onListClick)
list.addEventListener ('itemRollOver', onListRollOver)
cheers
